ART or MAKING- PAPER Boxns.

J mg Paper Boxes, of which the following is a specification. My inventionrelates boxes and has more particular reference to boxesof this character made of corrugated "board or other stiiimaterial and intended for use as containers for shipping matter by parcels post. It'wi-ll', however, be manifest,

as the invention is better understood, that it has a broader being capable of elficient use in numerous other connections.

provision of a strongand durable box of the general character described, which may be sheet of material without anyv'waste of said sheet in the cutting of successive blanks.

IAi furthe'rfobjectof the invention is the provision of a'box of this character which will have strongoverlappin flaps at its sides, said flaps .4 eing particu larly forined'to resist the rough handling of A further object of the invention is the provision of a suitable process for constructmg a box embodying my invention in an and without the Wasteof any of the box-forming materials. still further object is the provision, of

in general to paper and more general application,

- the finished box constructed-from blanks cut from a will be noted that blank therefore, v :laid out as indica-tedata and b inFig. 2, a

outwardly of the center of a 3 shows the blank folded and with the edges scored ready to be opened to form a finished box; I

- Fig. 4 is a view jof the box having the securing edge strip removed to show the relitiverelation of the top and bottom flaps;

Fig. 5.shows the completed box.

e box embodying my invention and shown on the drawing is of rectangular form,

, being slightlylong'er than it i s-wide. In the present instance,

this box'consists of two end walls 6, two side walls bottoms formed of flaps 8 on theedges of the side walls and-flaps 9 on the edges of the end-Wall's. These fiaps which this box is formedthe top and bottom. The edges of the side flaps 8 abut as do also the edges of the end' lary sealing strip 11 is required along one' of the vertical edges; scribed and embodying myv invention formed from asingle blank of the configuration shown in Fig. 2. 'From this figure it the blank is of double trapezoidal shape; each, trapezoidal part forming one-half of the container- The size and shape of this blank is 'determined as. fol,- lows: Theheight of each trapezoidal part or. the distance between its parallel sides isequal toxthe sum of the horizontal dimensions of a side and an end. In plannin a an end andside are rst 7 and tops and- ,are arranged in with abutting edges, so that I v two thic esses of corrugated ,-'board of A principal object of the present invention 20' is the equaling in superficial area and dimensions an end 6 and b equaling in superficial area and dimensions a side 7. The inclined lines formin the sides of each trapezoidal part are eaci determined by locating a point 0 lateral side of b a distance equal to one-half the length of thelateral side ofa, and a second point 03 located'outwardly of the center of a lateral side of aga distance equal one-half the length of a lateral side of band drawing a line through these two points intersecting the parallel sides of the trapezoidal part.

When a blank has been constructed in accordance with Fig. :2 and the foregoingdescription, one trapezoidal part one side of the strip or sheet from which the blanks are being cut and the tapering of the --terial'ofi.width equal to the combined maybe laid back over upon the other as indicated in Fig; 3 and the binding strip 11 of length equal to the over the edges the completed height of the box pasted thus adjoining. Thereafter box need only be ppened up, bringing a right angle at each line f and the flaps folded down into position.

, parts of the next toward the opposite side.

This effects not only-a substantial saving of the material but also a substantial 'sav-- ing in the cutting operation, as each successive out along the broken line formed by the side of the blank produces a completed blank, 't only being necessary in the strip to out completely across it to produce each blank.

It is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may be made in the forin,'construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing any of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.

I claim:

l. The process of making paperboxes from a continuous strip of material and without waste, which consists in cutting said strip into alternately reversed double trapezoidal sections, scoring and cutting said sections, foldlng on said scor ng and securing a pair' of adjacent edges in suitable fashion 60 I to form the box. a

2. The process of making paper boxes having double thicknesses of material at its top and bottom which consists of cutting double trapezoidal sections alternately reversed from a single sheet, scoring longi- This blankis scored centrally throughout its length along lines 6 defining of cutting a fine the height of the box,

trapezoidal one part coincident-with the wide edge of tudinally to define the-height of the and ends of the box, scoring transversely to define the lengths of the sides and'e-nds of the box, severing the material beyond the ends of the transverse score lines to define the flaps of the box, bending on the score lines and securing the opposite ends of the double trapezoidal sheet together.

3. The process of makingpaper boxes provided with abutting side and end flaps at the top and bottom of-the box, consisting blank of double trapezoidal form, scoring centrally longitudinally to deeach inclined edge of each trapezoidal part passing through a point beyond the center of the side edge, scoring a distance eqpal to one half the width of the end edge scoring and through a point beyond the center of the end edge scoring one-half the width of the side edge scoring. t. The process of making a paper box which consists in providing a double trapezoidal blank, scoring. the central part of said blank to form the body and cutting intothe inclined edges at. the, side of said. central part to. form the flaps. g Y 5. The process of constructing a paper box which consists in providing a, double trapezoidal blank, scoring and cutting each trapezoidal part to form one-half offsaid' box, folding one trapezoidal part upon the other. 6. The process of making a -'paper ,box which consists in constructing a double blank with the narrow edge of the other, and scoring and cutting said blank to form "the box.

7. Theprocess of making a paper box without waste, which consists in providing a sheet of material of width equal to the perimeter of the box, cutting said sheet into a series of blanks on broken lines, said lines being successively of like delineation alterna'tively reversed.

8. A process of making paper boxes from acontinuous strip of material and withoutsides and from one to the other of the first mentionedscores, and cutting said sections in continuation of the last mentioned scores to the non-parallel sides of the sections; and then folding each double section and secur ing together its free parallel ends.

9. A process of making paper boxes from V a continuousstrip of material and without waste, which consists in cutting said strip into alternately reversed double trapezoidal sections: .then scoring said sections on lines extending from side to side of the parallel sides of the double sections, and allel ends, and folding said sections on said on the lines extending parallel with said scores to form box-like inclosures. 1e parallel sides and from one to the other of Signed in the presence of two subscribing the first mentioned scores, and cutting said wltnesses.
